Preliminary deep-sea data analysis collected at Gloria seamount, Azores-Biscay ...
Tojeira, Inês; Pinto Ribeiro, Luísa; Rafael, Teresa; Albuquerque, Mónica; Simões, Maria; Calado, António; Afonso, Andreia; Ramos, Bruno; Souto, MiguelThe present study provides the first results of the exploratory research campaign to Gloria seamount (summit at 45.03°N, 15.54°W), a newly identified seamount in the NE Atlantic. New multibeam bathymetry and an 8 h remote operated vehicle footage and photography data were compiled and analyzed to give the first insights on the geological nature and benthic megafauna assemblages of Gloria seamount. Footage evide...
Mineralogy and Geochemistry of High-Temperature Cu-rich Hydrothermal Chimneys f...
González, Javier; Somoza, Luis; Medialdea, Teresa; Santofimia, Ester; Rincón-Tomás, Bianca; Marques, Filipa; Pinto Ribeiro, Luísa; Calado, AntónioThe Moytirra hydrothermal vent field is located on the Mid-Atlantic Ridge (MAR) at approximately 45°N, between the Azores and Iceland. This system was discovered in 2011 during an Irish-led scientific expedition aboard the RV Celtic Explorer, and was later extensively explored and sampled in 2019 by the Spanish EXPLOSEA 2 expedition aboard the RV Sarmiento de Gamboa, with the support of the remotely operated ve...
Analysis of patellar reflex in Parkinson disease patients after an acupuncture ...
Pereira, Catarina Ramos; Reis, Ana Mafalda; Machado, Jorge; Ramos, Bruno; Criado, Begona; Santos, Maria João; Santos, Rubim; Greten, Henry JohannesThe investigation of rigidity physiology in Parkinson’s Disease involves the examination of reflexes. Parkinsonian patients often demonstrate reduced sensitivity in polysynaptic reflexes within the leg extensor muscles, which is correlated with their postural instability. The compensatory mechanisms for impaired proprioceptive reflex function may involve alterations in intrinsic muscle stiffness. The interplay ...
Influenza A virus propagation requires the activation of the unfolded protein r...
Marques, Mariana; Ramos, Bruno; Albuquerque, Hélio; Pereira, Marisa; Ribeiro, Diana Roberta; Nunes, Alexandre; Sarabando, Jéssica; Brás, DanielaInfluenza A virus (IAV) employs multiple strategies to manipulate cellular mechanisms and support proper virion formation and propagation. In this study, we performed a detailed analysis of the interplay between IAV and the host cells’ proteostasis throughout the entire infectious cycle. We reveal that IAV infection activates the inositol requiring enzyme 1 (IRE1) branch of the unfolded protein response, and th...
Acupuncture effect on reaction-time changes in Parkinson’s disease patients—Cas...
Pereira, Catarina Ramos; Greten, Henry J.; Santos, Rubim; Reis, Ana Mafalda; Ramos, Bruno; Santos, Maria João; Machado, Jorge; Criado, Maria BegoñaParkinson’s Disease (PD) is a progressive neurodegenerative condition associated with deficit in reaction time which can lead to falls, resulting in limited independence, diminished quality of life, heightened rates of institutionalization and increased healthcare costs. We aimed to examine the effects of an acupuncture protocol in motor time response after an auditory stimulus. Methods: This study employed a c...
Tools to Investigate the Peroxisome-Dependent Antiviral Response
Ramos, Bruno; Ferreira, Ana Rita; Ribeiro, DanielaThe importance of peroxisomes in the context of viral infections has been increasingly demonstrated in recent years. The discovery that MAVS localizes at peroxisomes and that peroxisomal and mitochondrial MAVS perform complementing functions within the antiviral response has raised the interest in studying the peroxisome-dependent signaling in the context of infection by different viruses. To that end, specific...

Multidisciplinary Scientific Cruise to the Northern Mid-Atlantic Ridge and Azor...
Somoza, Luis; Medialdea, Teresa; González, Javier; Calado, António; Afonso, Andreia; Albuquerque, Mónica; Bettencourt, Renato; Blasco, IkerThis work presents the preliminary result of the multidisciplinary cruise EXPLOSEA2 surveying the northern Mid-Atlantic Ridge and Azores Archipelago from 46 300 N to 38 300 N aboard the R/V Sarmiento de Gamboa and ROV Luso over 54 days (June 11 to July 27, 2019). In this cruise report, we detail the geophysical, hydrographic, geological, oceanographic, ecological, and microbiological data acquired and a brief o...
High-resolution multibeam bathymetry of the northern Mid-Atlantic Ridge at 45–4...
Somoza, Luis; Medialdea, Teresa; González, Javier; Marchancoses, Sara; Candón, Jose; Cid, Constantino; Calado, António; Afonso, AndreiaThis work presents a new high-resolution multibeam bathymetric map of a segment of active deep sea-floor spreading in the Atlantic Ocean, the northern Mid-Atlantic Ridge (MAR) at 45–46º N. New high-resolution bathymetry data were acquired using an Atlas multibeam echosounder onboard the research vessel Sarmiento de Gamboa during the EXPLOSEA-2 survey in 2019. The final map of the MAR (50 m cell grid size) at th...
Emerging roles of peroxisomes in viral infections
Ferreira, Ana Rita; Marques, Mariana; Ramos, Bruno; Kagan, Jonathan C; Ribeiro, DanielaPeroxisomes, essential subcellular organelles that fulfill important functions in lipid and reactive oxygen species metabolism, have recently emerged as key players during viral infections. Their importance for the establishment of the cellular antiviral response has been highlighted by numerous reports of specific evasion of peroxisome-dependent signaling by different viruses. Recent data demonstrate that pero...
